元古宙爆破角砾岩型店坊金矿床中的黄铁矿是主要载金矿物。黄铁矿多为{100}，属硫亏损型（Fe(1.0000)S(1.8775－1.9821)），Co／Ni＞1（1．5－5．875），热电系数导型为N型，S＝4.8‰～6.8‰，形成于温度较高（220~438℃）、氧逸度为logfo2＜－37×105Pa、硫逸度为lgfs2=-39.85105～-35.65×1O5Pa、氧化还原条件发生变化的开放系统中。这是与熊耳群岩浆侵入．火山喷发活动有关的爆破角砾岩型金矿成矿作用演化的记录和标志。
Proterozoic brecciated breccia-type gold deposits in the Fangfang pyrite is the main gold-bearing minerals. Most of pyrite are {100}, belonging to sulfur depletion type (Fe (1.0000) S (1.8775-1.9821)), Co / Ni> 1 = 4.8 ‰ ~ 6.8 ‰, formed at high temperature (220 ~ 438 ℃), oxygen fugacity logfo2 <-37 × 105Pa, sulfur fugacity lgfs2 = -39.85105 ~ -35.65 × 1O5Pa, the redox conditions change Open system. This is in contact with the Xiong’er Group magma. Records and Signs of Evolution of Mineralization of Blast breccia Type Gold Deposit Related to Volcanic Eruptions.
